COMPILER, COMPILE METHOD, COMPILE PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To optimize much more instruction columns to processing when variables are specific values for compilation. SOLUTION: This optimization compiler is provided with an update instruction detecting part which detects an update instruction to update the contents of variables and a storage region designated by the variables in a program to be optimized, an instruction column detecting part for detecting an instruction column for executing different processing according to the contents of the variables or the storage region when control is shifted by a control shift instruction for shifting control to another instruction column in the target program, an instruction column compiling part for optimizing the detected instruction column to processing when the contents of the variables or the storage region are preliminarily decided specific contents for compilation and a setting instruction generating part for generating a setting instruction to be executed when the contents of the variables or the contents of the storage region are specific contents from the update instruction to the control shift instruction in the object program for setting the shift destination address of the control shift instruction to the address of the instruction column optimized by the instruction column compiling part.
